3 claims.

This invention relates to weather strip means for Windows, such as areused in railway cars and busses, and particularly a weather strip meansbetween the lower rail of an upper sash and the top rail of a bottomsash to seal the joint between the sashes when the movable sash, usuallythe lower sash is closed, and has for its object, a fibrous or clothcovering for a thin iiexible spring leaf which is purposely easilydistorted to conform to unevennesses on the contact surface of the sashwith which the leaf engages, which covering compensates for distortionand keeps the joint between the sash tight, regardless of thedistortions.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawing, in which like characters designate corresponding parts in allthe views.

Figure 1 is a fragmentary elevation, partly in section, of a windowconstruction embodying this invention.

Figure 2 is an enlarged, sectional viewv on line 2 2, Figure 1.

Figure 3 is an enlarged, sectional view on line 3 3, Figure 1.

Figure 4 is an enlarged, fragmentary, isometric view of the weatherstrip.

l designates generally, the window frame, which may be of any suitableform, size and construction, it being provided with suitable sashguides.

2 is a hollow sash, which is capable of being raised and lowered.

3 is an upper sash, or any other element, having a lower rail, as 4, forlapping the top rail 5 of the lower sash 2, when the sash 2 is closed.

The weather strip means comprises a thin, flexible, resilient,distortable, sheet metal backing or strip 'l secured to one of the rails4, 5, usually the rail 4, and extending between the rails, the stripbeing usually of thin sheet brass with suiiicient resiliency to pressits free end outwardly against the rail 5. The strip 1 includes a baseportion 8 secured to the rail 4, and a leaf portion 9 projecting fromthe base portion and tensioned outwardly toward the rail 5, the leafportion being covered with a fibrous material as cloth, or felt l0,extending around the free edge of the leaf portion and on the rear sideof the leaf portion, as at Il. This covering is secured to the strip, orthe leaf portion, usually by cementing.` Also, the margin of the leafportion (Cl. 18S-65) is preferably flexed slightly, as at I2, tofacilitate the cementing of the covering to the leaf portion at themargin thereof in order that the covering will more securely adhere tothe leaf portion at the margin thereof.

The base portion 8 extends between the stiles I3 of the upper sash, andis here shown as secured to the upper sash by seating in the glassreceiving groove of 'the upper sash, so that the strip is secured to theupper sash by the glass pane. In order that the leaf portion strip 9 mayextend the full width of the sashes, and not leave air gaps at the endsthereof, the leaf portion is providedV with extensions I4 which extendover the stiles of the upper sash and permit the leaf portion to alsolap the full width of the lower sash between the stops. Ordinarilyfibrous weather strips of carpeting and the like, or material having anap,

compresses very quickly, so that they are loose and ineicient inperforming their function aS a weather strip. Also,` flexible strips areinherently distorted or wavy and become indented, distorted, or wavy attheir edges due to unevenness ofthe top rail ofthe lower sash formed bydust etc., adhering to the top rail, thus providing passages for airdrafts, so that the strip is not efficient.

By my invention, the fibrous or cloth covering for a thin, resilient,distortable, strip compensates for wear of the covering by reason of theresiliency of the strip and also, compensates for distortion etc., ofthe strip so that the joint between the sashes remains weather tight andefficient practically the entire life of the sash.

What I claim is:

1. In a window construction, the combination with a window frame, andupper and lower sashes mounted in the frame, one of the sashes beingmovable, and the bottom rail of the upper sash lapping the top rail ofthe lower sash when the movable sash is closed; of weather strip meanscomprising a thin, flexible, resilient, and distortable, metal striphaving a base portion fixed to the rail of one sash between the Stilesof that sash, and a leaf portion extending between the rails andtensioned to press its free end toward the other rail, the leafportion'having'extensions at its ends extending over the Stiles of thesash to which the strip is secured.

2. In a window constructiom the combination with a window frame, andupper and lower sashes mounted in the frame, one of the sashes beingmovable, and the bottom rail of the upper sash lapping the top rail ofthe lower sash when the movable sash is closed; of weather strip meanscomprising a thin, flexible, resilient, and distortable metal striphaving a base portion fixed to the rail of one sash between the stilesof that sash, and a leaf portion extending between the rails andtensioned to press its free end toward the other rail, the leaf portionhaving extensions at its ends extending over the stiles of thev sash towhich the strip is secured, and a cloth covering on the leaf portion. Y

3. In a window construction, the combination with a window frame, andupper and lower sashes mounted in the frame, one of the sashes beingmovable, and the bottom rail of the upper sash lapping the top rail ofthe lower sash when the movable sash is closed, a weather strip comprising a thin, flexible, resilient, and distortable metal strip having abase portion fixed to the rail of one sash between the stiles of thatsash, and a leaf portion extending between the rails and tensioned topress its free end toward the other rail, the strip having extensions atits ends extending over the stiles of the sash to which the strip issecured, and a cloth covering on the leaf portion, said cloth coveringextending from the base portion over the outer face of the leaf portion,around the free edge of the leaf portion and lapping the rear sidethereof.
